What the interaction means

Ciprofloxacin's FDA label lists "potassium elevation (serum)" only among post-marketing laboratory-abnormality adverse-event reports for ciprofloxacin itself, not as a documented interaction with potassium supplements. The NIH ODS potassium fact sheet does not mention ciprofloxacin or quinolones.

No documented interaction between Ciprofloxacin and Potassium was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.

Practical context

The ciprofloxacin label's isolated serum-potassium adverse-event listing is a lab-abnormality report, not an interaction claim, so it is deliberately not treated as one here -- both substances' own current authoritative sources were checked directly, full text, in both directions.
